Robert Wille created CASSANDRA-10442:
----------------------------------------
Summary: Paging returns duplicate records
Key: CASSANDRA-10442
URL: https://issues.apache.org/jira/browse/CASSANDRA-10442
Project: Cassandra
Issue Type: Bug
Reporter: Robert Wille
When I execute "SELECT image FROM roll WHERE roll = ?" against
CREATE TABLE roll (
roll INT,
image BIGINT,
data VARCHAR static,
PRIMARY KEY ((roll), image)
) WITH gc_grace_seconds = 3456000 AND compaction = { 'class' :
'LeveledCompactionStrategy', 'sstable_size_in_mb' : 160 };
The image returned from the query is duplicated every fetchSize records (i.e.
1, 2, 3, 3, 4, 5, 6, 6, etc). I can reproduce this easily 100% of the time in
Cassandra 2.0.16 with Java Driver 2.0.11 and RF=3 and CL=QUORUM or ONE. If you
need sample code, I can provide, but given the simplicity, I suspect it will be
easy to reproduce.
I realize this bug might be in the Java driver, but I don't know, so I'm
logging it here.
